This type definition looks pretty much OK.

...and this is a very strange idea: struct types contain fixed number
of named fields, so
s := struct{
// what's this?
}

This is possible but arguably don't needed.
If all you need is merely a slice of Server instances,
just use it.

In the simplest case:
s := []Server{
Server{
Name: "Arslan",
ID: 123456,
Enabled: true,
},
...
}
If you need your nested structs, then
s := Servers{
servers: []Server{
Server{
Name: "Arslan",
ID: 123456,
Enabled: true,
},
...
}
}
